Drupal should be making the RSS feed for you. Look at http://www.yourdomain.com/rss.xml and see if one loads up. If not there might be a setting in the Admin area to turn on the RSS feed.
Ok so drupal does infact make an rss feed, but it also shows my google pub id, how do i remove that? Thanks.
The Google code is in your Description field, so you might want to look in the Admin section and see if you can find a site description area and see if there is code in there. Also you might want to look at where you had placed the Google code. Where you put it might be why it is showing up in the RSS feed and you may need to move it some where else to get it out of the RSS feed.
